Xiaomi Gateway - Setting light color

[misfit]

I can dim the light with 'level (%)' but how to set RGB color? (Tried to put hex value in 'number' block but seems thats not the right way

Thanks!

i make it in dzvents scripts with this code:

Code: Select all

 local sceneCmd = 'curl -s -i -H "Accept: application/json" "http://192.168.1.4:8084/json.htm?type=command&param=setcolbrightnessvalue&idx=20&hue=236&brightness=1&iswhite=false"'
os.execute(sceneCmd)

change the ip and port to conect
change the idx (20 in my case)
change de colour (236 in my case)
and change the brightness (1 in my case)

I see this skeleton when creating a new dzvents script:

Code: Select all

return {
	on = {
		devices = {
			'myDevice'
		}
	},
	execute = function(domoticz, device)
		domoticz.log('Device ' .. device.name .. ' was changed', domoticz.LOG_INFO)
	end
}

How to utilize your code, if lets say i want to set the color when a user variable changing? (I set the variable with a timed blocky event.)

Hi,

i also try to set the colour of the Xiaomi Gateway with a LUA Script.
But i can only set the brightness with:

commandArray['Xiaomi RGB Gateway']='Set Level:100'

I also tried to set RGB values with Set Level but it does not work.
I don't know which command is needed to set this configuration.

Can some one explain me how to find out this information? Maybe also basicaly how to do it on other devices?

Logfile only shows Set Level if i change the colour in the web interface.

thx.

Hello,

i am again.

I also tried this in my lua script:

Code: Select all

        	local sceneCmd = 'curl -s -i -H "Accept: application/json" "http://192.168.178.55:9898/json.htm?type=command&param=setcolbrightnessvalue&idx=1&hue=236&brightness=100&iswhite=false"'
			exec_success = os.execute(sceneCmd)

But the LED light don't switch on and the variable exec_success is nul.

How can i test this os command separately?
If i try it on my console and get no error.

Domosticz is running on an raspi 1. And connected to Xiaomi Gateway V2.

Any ideas?

Thx.

y use this comand in a dzvents script and works perfect

Hi,

i get running this command in my lua device script.
But sometimes i get an error => scirpt run for more then 10 seconds ....

Is my raspi 1 to slow???
Some one same experiance? Maybe any ideas?

Thx.

Hi,
Can you add some printscreens = examples how they work?
Thanks

[Schorschi]

Hi,

here an example of my lua script.
Addapt your ip and port of your domoticz device

Code: Select all

Red   =  	0xFF0000 	--(255,0,0)
GatewayColour = Red

		local sceneCmd = 'curl -s -i -H "Accept: application/json" "http://192.168.10.1:8080/json.htm?type=command&param=setcolbrightnessvalue&idx=1&hex=0x'..string.format("%x", GatewayColour)..'&brightness=100&iswhite=false"'
		os.execute(sceneCmd)

Thanks mate, but i am absolute beginner , try to write first script ever .Can you add complete from A to Z script?

[hekm77]

If interesting, You can try.
You must create two Dummy Switch, type - Dimmer: miGateway Hue and miGateway Bri
In the script , enter your username, password, ip and port domoticz.

Hi,

to set color for the xiaomi gateway is not working in the last domoticz beta and current gateway fw.
I try it with my old script but can't change the color. The gateway switch always to the last manually selected color.

Code: Select all

		---------------------------------------------------------------------------------------------------
		-- Gateway Colour
	       commandArray['Xiaomi_RGB_Gateway']='Set Level:'..tostring(GatewayBrightness) -- set brightness LED light from Gateway

		-- change colour of gateway
		local sceneCmd = 'curl -s -i -H "Accept: application/json" "http://192.168.178.62:8083/json.htm? 
                type=command&param=setcolbrightnessvalue&idx=1&hex=0x'..string.format("%x", GatewayColour)..'&brightness=100&iswhite=false"'
		os.execute(sceneCmd)

any idea?
